BACKGROUND 1. Field

The present disclosure relates to layout generation and management of User Interfaces (UI) for electronic devices, more particularly, but not exclusively to a method and system for generating dynamic User Interface (UI) layout for an electronic device.

2. Description of Related Art

A Graphical User Interface (GUI) is a system of interactive visual components for computer software. A GUI displays objects that convey information and represent actions that can be taken by a user. The objects change color, size, or visibility when the user interacts with the objects. GUI objects include icons, cursors, and buttons. These graphical elements are sometimes enhanced with sounds, or visual effects like transparency and drop shadows. Generally, user interface elements fall into one of the following four categories, i.e., Input Controls (ICs), Navigation Components (NCs), Informational Components and Containers (ICC).

User Interface (UI) elements can be displayed by a graphical user interface of a computing device and interacted with users of the device. A mobile UI allows a user to interact with applications, features, contents, and functions of the mobile device. In computer applications, a list of user interface (UI) elements accomplishing various functionalities are often shown at the same place, for example, the same window, menu, frame, tab, or pane. Thus, the displays of UI elements are limited in their usefulness to various users.

Currently, the UI layouts are defined statically. Existing systems concentrate on placement of text on image, based on a Region of Interest (ROI). The existing UI layout generation systems do not consider user interaction pattern for optimal compositions for device factors which are very crucial during handling of multiple form factors.

Hence, there is a need to develop user interfaces for each form factor and for managing a UI for foldable devices, where different modes such as, Augmented Reality (AR) mode, Desktop Experience (DEX) etc., can be handled by one system. Therefore, improvements in the display of UI elements would be useful.

The information disclosed in this background of the disclosure section is only for enhancement of understanding of the general background of the inventive concept and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

Embodiments of the present disclosure relate to a method and a system for generating dynamic User Interface (UI) layout for an electronic device. Generally, a layout defines a structure for a user interface in any electronic device and allows a user to interact with the electronic device.

Currently, the UI layouts are defined statically. Particularly, existing systems concentrate on placement of text on image, based on a Region of Interest (ROI) without considering user interaction pattern for optimal compositions for device factors which are crucial during handling of multiple types of devices. The present disclosure in such condition focuses on identifying an optimal region from a plurality of candidate regions for layout composition based on user interaction pattern. The plurality of candidate regions are identified based on a saliency score and an aesthetic score, which are calculated based on a current display screen of the electronic device. The present disclosure generates a dynamic UI layout in order to perform operations related to the at least one UI element in the optimal region. As a result, the present disclosure helps in building visually pleasing intuitive UI based on saliency, aesthetics, and user interaction grid, which enhances the readability on the electronic device.

FIG. 1 illustrates an exemplary block diagram of an electronic device for generating dynamic User Interface (UI) layout in accordance with some embodiments of the present disclosure.

Specifically, FIG. 1 illustrates an electronic device 100 comprising a layout generation system 101. In an embodiment, the electronic device 100 referred herein may be any computing device associated with users. For example, a laptop, a notebook, a smartphone, a wearable device, a tablet, and any other computing devices. A person skilled in the art would understand that the scope of the present disclosure may encompass any other electronic device 100, not mentioned herein explicitly, which includes UI layout for interaction with a user. The electronic device 100 includes a display 109 (interchangeable referred as display screen) apart from other components, which are not shown specifically in FIG. 1. The layout generation system 101 includes an Input/Output (I/O) interface 103, a processor 107 and a memory 105 for storing instructions executable by the processor 107. The I/O interface 103 is coupled with the processor 107 through which an input signal and/or an output signal is communicated.

In an embodiment, the user may communicate and interact with the electronic device 100 using various UI elements present in the UI of the electronic device 100. Typically, placement of one or more UI elements is based on various factors including a specific type of the display screen 109 of the electronic device 100, for instance, home screen, lock screen, applications screen, and the like. The layout generation system 101 may be used in the electronic device 100 for generating dynamic UI layout in the electronic device 100. In an embodiment, the layout generation system 101 may be a computing unit configured within the electronic device 100.

At any given instant, when the electronic device 100 is being used by the user, the layout generation system 101 may determine a current state of the display screen 109 of the electronic device 100, that is, what state the display screen 109 is in currently, and which UI elements are associated with the current state. In an embodiment, the UI elements are interactive components for providing interactivity to user interface. For instance, the least one UI element may include icons, notifications, widgets, navigation components, input controls and the like. The current state of the display screen 109 may be, for example, one of the lock screen, home screen, middle part of an application page and the like. Additionally, a frame associated with the display screen 109 is determined based on the current state of the display screen 109.

Based on the determined current state of the display screen 109, the layout generation system 101 identifies one or more operations related to at least one UI element. The one or more operations may include displaying the at least one UI element, re-arrangement of at least one UI element on the display screen 109 and the like.

Further, the display screen 109 of the electronic device 100 is divided to form a plurality of grids based on parameters associated with the at least one UI element. The parameters associated with the at least one UI element may include size, transparency, and interactability with users. For each of the plurality of grids, the layout generation system 101 calculates a saliency score which corresponds to prominent features in the display screen 109 and an aesthetic score corresponding to a region with ideal placement possibilities on the display screen 109. The layout generation system 101 utilizes pre-trained machine learning models for calculating the saliency score and the aesthetic score for each of the plurality of grids.

In some embodiments, the layout generation system 101 identifies a plurality of candidate regions based on the calculated saliency score and the aesthetic score. The plurality of candidate regions are utilized in performing the one or more operations related to the one or more UI element. Amongst the plurality of candidate regions, the layout generation system 101 identifies an optimal region based on a user interaction score. In an embodiment, the optimal region may refer to a region in the display screen 109 which is suitable for performing the one or more operations related to the at least one UI element. The user interaction score corresponds to a region comprising locations with pre-determined accessibility threshold and is determined based on pre-determined user behavior related to usage of the electronic device 100. The user interaction score may be determined using a machine learning model, which may be trained with predetermined user behavior related to usage of the electronic device 100.

Particularly, the layout generation system 101 calculates a composition score based on the saliency score, the aesthetic score and the user interaction score and identifies the optimal region based on the composition score. Thereafter, the layout generation system 101 generates the dynamic UI layout by performing the one or more operations related to the at least one UI element in the optimal region. Thus, the present subject matter makes use of user interaction pattern for optimal layout compositions. For instance, consider if the one or more operation is for re-arrangement of the at least one UI element in the electronic device 100. The layout generation system 101 may receive an input either from the electronic device 100 or from the user explicitly to trigger re-arrangement of the at least one UI element in the electronic device 100. In such case, the layout generation system 101 may determine locations of the plurality of candidate regions and of the optimal region and identify current position of the at least one UI element in relation to the plurality of candidate regions and the optimal region. Thereupon causing the at least one UI element to move away from the one or more candidate regions. Alternatively, consider if the one or more operation is displaying the at least one UI element in the electronic device 100. The layout generation system 101 may identify the at least one UI element currently being displayed on the electronic device 100. Consider if the least one UI element and an image content are being simultaneously displayed on the electronic device 100. In such case, the layout generation system 101 may cause the at least one UI element to be displayed on the identified optimal region.

FIG. 2 shows a detailed block diagram of a layout generation system in accordance with some embodiments of the present disclosure.

The layout generation system 101 may include data 200 and one or more modules 209 which are described herein in detail. In an embodiment, data 200 may be stored within the memory 105. The data 200 may include, for example, display screen data 201, learning models 203, candidate region data 205, optimal region data 207 and other data 208.

The display screen data 201 may include information about the current state of the display screen 109 on the electronic device 100. The state of the display screen 109 may be lock screen, home screen, application page and the like. Further, the display screen data 201 may include frame details based on the current state of the display screen 109. Further, the display screen data 201 may include information about the at least one UI element associated with the current state of the display screen 109.

The learning models 203 may include a saliency score machine learning model and an aesthetic score machine learning model for providing respective scores for the plurality of grids.

The candidate region data 205 may include information about the plurality of candidate regions which are identified from the plurality of grids for the display screen 109 based on the saliency score and the aesthetic score. For instance, the information may include pixel or location details for such plurality of candidate regions.

The optimal region data 207 may include information about the region which is identified as optimal among the plurality of candidate regions. The information may include, for instance, pixel or location associated with the optimal region.

The other data 208 may store data, including temporary data and temporary files, generated by modules 209 for performing the various functions of the layout generation system 101.

In an embodiment, the data 200 in the memory 105 are processed by the one or more modules 209 present within the memory 105 of the layout generation system 101. In an embodiment, the one or more modules 209 may be implemented as dedicated units. As used herein, the term module refers to an application specific integrated circuit (ASIC), an electronic circuit, a field-programmable gate arrays (FPGA), Programmable System-on-Chip (PSoC), a combinational logic circuit, and/or other suitable components that provide the described functionality. In some implementations, the one or more modules 209 may be communicatively coupled to the processor 107 for performing one or more functions of the layout generation system 101. The modules 209 when configured with the functionality defined in the present disclosure will result in a novel hardware.

In one implementation, the one or more modules 209 may include, but are not limited to a communication module 211, a UI element operation identification module 213, a saliency score calculation module 215, an aesthetic score calculation module 217, a candidate region identification module 219, an optimal region identification module 221 and a layout generation module 223. The one or more modules 209 may also include other modules 225 to perform various miscellaneous functionalities of the layout generation system 101. In an embodiment, the other modules 225 may include a display screen determination module and a training module. The display screen determination module determines the current state of the display screen 109 on the electronic device 100. The training module may train the machine learning models for calculating the saliency score, the aesthetic score, and the user interaction score.

The communication module 211 may obtain one or more implicit inputs from the electronic device 100 and from the user of the electronic device 100.

The UI element operation identification module 213 may identify the one or more operations related to at least one UI element based on the current state of the display screen 109. In an embodiment, the one or more operations may include displaying the at least one UI element and re-arrangement of at least one UI element on the display screen 109. In case of re-arrangement request, the at least one UI element may be caused to move away from the optimal region.

The saliency score calculation module 215 may calculate the saliency score for each of the plurality of grids determined on the display screen 109, by using the pretrained machine learning model. The saliency score for each of the plurality of grids is calculated based on heatmap output of the saliency score machine learning model. Particularly, the heatmap output is used to identify a region of feature density scoring respective cells. FIG. 3A shows an exemplary representation for machine learning model for generating saliency heatmap in accordance with some embodiments of the present disclosure. As shown, FIG. 3A shows exemplary three images, features of which are fed as input to the saliency score machine learning model. In an embodiment, the saliency score machine learning model may be trained using deep learning mechanism. As shown in FIG. 3A for instance, the saliency score machine learning model includes different Convolutional and De-Convolutional blocks for calculating the saliency heatmap value, where the heatmap value for each grid cell of the image is the saliency score.

The aesthetic score calculation module 217 may calculate the aesthetic score for each of the plurality of grids determined on the display screen 109 by using the pretrained machine learning model. Particularly, the aesthetic score corresponds to a region with ideal placement possibilities. The aesthetic score for each of a plurality of grids is calculated based on heatmap output of the aesthetic score machine learning model. Particularly, the heatmap output is used to identify ideal placement possibilities aesthetically. FIG. 3B shows an exemplary representation for machine learning model for generating an aesthetic score in accordance with some embodiments of the present disclosure. As shown, FIG. 3B shows an exemplary image, features of which are fed as input to the aesthetic score machine learning model. In an embodiment, the aesthetic score machine learning model may be trained using deep learning mechanism. As shown in FIG. 3B, for instance, the aesthetic score machine learning model includes different Convolutional and De-Convolutional blocks for calculating the aesthetic score.

The candidate region identification module 219 may identify the plurality of candidate regions based on the calculated saliency score and the calculated aesthetic score. FIG. 4A as described below in detail shows how the saliency score, the aesthetic score and the user interaction scores are combined to calculate the composition score. In an embodiment, pre-learned weights may be used for summation of these three scores as weighted summation (CS_(ij)). Thus, grid cells with maximum scores are considered for candidate regions.

The optimal region identification module 221 may identify the optimal region for the dynamic UI layout from the plurality of candidate regions. Particularly, the optimal region identification module 221 identifies the optimal region based on the user interaction score. The optimal region identification module 221 may determine the user interaction score for the display screen 109 based on pre-determined user behavior of usage of the electronic device 100. In an embodiment, the optimal region identification module 221 may determine the user interaction score by using an interaction score machine learning model, particularly based on heatmap output from the machine learning model. The interaction score machine learning model may be trained previously using plurality of user interaction behavior associated with usage of the electronic device 100. The interaction score machine learning model may be trained for pre-determined accessibility threshold, such as, highly interactable region, medium and low interactable region. Thus, the interaction score corresponds to region comprising locations with pre-determined accessibility threshold. FIG. 3C shows an exemplary embodiment for generating a user interaction score in accordance with some embodiments of the present disclosure. FIG. 3C shows a mobile device 300 with a display screen 301 of a website page, which includes one or more UI elements. Based on the user interaction behavior associated with usage of the electronic device 100, i.e., how often the one or more UI elements are utilized by the user, the optimal region identification module 221 may determine a frequency map for the grids of the display screen 301 based on user interaction behavior in order to determine the user interaction score for the display screen 301. The user interaction region which are highly utilized by the user is shown as highlighted in the display screen 301.

Thus, upon determining the user interaction score, the optimal region identification module 221 calculates the composition score, which is a weighted average based on the saliency score, the aesthetic score, and the user interaction score. The optimal region identification module 221 identifies the optimal region based on the composition score.

The layout generation module 223 may generate the dynamic UI layout by performing the one or more operations related to the at least one UI element in the optimal region.

FIG. 4A shows an exemplary representation for generating dynamic User Interface (UI) layout in accordance with some embodiments of the present disclosure.

FIG. 4A shows an exemplary embodiment for generating dynamic User Interface (UI) layout. As shown, the embodiment includes a current lock screen 401 of the electronic device 100. The lock screen 401 includes a background image and an application layout such that date and time are placed above the background image. In case the layout generation system 101 receives a re-arrangement request from the user from placement of the application layout, i.e. date and the time within the background image, the layout generation system 101 may dynamically generate the requested UI layout by identifying an optimal region based on the composition score using the saliency score, the aesthetic score and the user interaction score. Thus, accordingly, the layout generation system 101 provides the dynamic UI layout with the placement of application layout in the background image as shown by final composition screen 403. Similarly, considering another scenario, where the UI element may be a layout within an application window or window of other application. For instance, notification bubbles from applications may be rearranged according to an optimal region for background application. In addition, dynamic layout may be generated based on bubble placement as shown in FIG. 4B. FIG. 4B shows an exemplary UI layout generation in accordance with some embodiments of the present disclosure. As shown in FIG. 4B, a mobile device with display screen 407 includes keypad along with a touch assistive icon 405. The touch assistive icon 405 as seen is placed on one of the alphabetic element, thus causing interactive issues to the user. In such case, based on the saliency score, the aesthetic score and the user interaction score, the layout generation system 101 may determine the optimal region and performs re-arrangement of the touch assistive icon 405 without obscuring other touchable elements. The display screen 407 with dynamic layout generation is represented as a display screen 409 with re-arrangement of the touch assistive icon 405 away from the touch alphabetic element.

In an embodiment, the present disclosure may also be applicable for other use cases, such as, when a state of the electronic device 100 changes in foldable devices.
